Help: Flying Car Hybrid Prototype

Prototype for my flying car hybrid. To operate, there are 6 controls.
- Controls on the RIGHT control driving mechanics
- bottom right slider is the control for switching between having wheels like a regular car/flying
- Controls on the LEFT control flying mechanics
- F is fowards
- G is backwards

Help: I'm trying to make this be able to fly and drive, but I'm having trouble having a stable hover, and I think I messed up the connections somewhere
